I found this via a Google search the other day, and I'm confused because I can't figure out exactly where it came from.
There was a DC-specific World's Greatest Super Heroes Health Tips book, which the Shrine talked about way back in 2007. I have that book, and it doesn't feature this image at all--so what is it? The same book with a different cover? That seems unlikely, so where did this thing run? It's clearly the work of Neal Adams and Dick Giordano, which means it's gorgeous--and Aquaman is dead center!
